1 英语连接词
　　英语有100万个单词，而连接词却只有70个左右，它们总是非常高频率的出现在各类文章、对话、电邮等英语实际沟通中，像胶水一样将相关联的句子连接起来，国际心理学家、语言学家、教育家Chris Lonsdale 龙飞虎又把它称之为“胶水词”。胶水词就像英语的骨架一样重要，学会了胶水词，同时拥有词组的累积，你就可以轻松灵活的造出任何需要的长句，让你的英文交流如鱼得水。先学胶水词，也是英语速成的窍门之一。为了快速掌握词组和连接词的用法，我们需要运用到一个数学方法——括号法，该方法可以帮你明白如何剖析英语长句，以及如何运用胶水词创造自己的的长句。例如：(The bicycle track) (is) (between) (the road) (and) (the river). 这个句子所要表达的只有3个东西之间的关系，括号能帮你分清楚什么内容代表“东西”以及什么内容代表“关系”。复杂的从句同样可以用括号法理清内部架构，从而掌握从句的逻辑和背后沟通的意思。
